So in retrospective do you think it was a wrong decision to make a laptop without a floppy drive? Or the one without COM/LPT ports? Or the one without optical drive? This is quite similar.
I don't actually find those as similar personally.
From my personal memory, those were all far less disruptive to my workflows at the time. It was so long ago it's hard to really think about and compare honestly.
The point remains - the USB-C "future" could have been enjoyed equally well with just adding one or two of those to an existing port lineup. Nothing necessatied the inconvenience of "only" USB-C for all laptop models (this last part is a big part of the issue). That was also 3 years ago and it's still a pain for many of us. It was definitely too early in 2016. I'd probably be more ok with it now - vs then for sure.
Thin/lightweight/amazing machines (with better keyboards) exist right now on the PC side. Apple didn't "need" to go USB-C only to make something light/thin/sexy - that's just what all USB-C fans hold up as "why" - and it's not true.
